This invention relates to a combined. terrestrial globe and directreading clock mechanism for mdicating the time in various parts. &- theworld.

An object of the invention is to provide. a; new and improvedterrestrial globe clock .of the vabove character in. which the. timeindicator iscombmed with the structure: so thatit can be readllyvisieble and at the same: time retain an. unobstructed view of the globe.

Another object is to provide a globe'xclockqof the above characterwherein the cloclrmechan-ism is disposed within the globe and the globebase in such manner that the globe may .be turnedlior examination ofdifferent .parts thereof. l without afiecting the operation of the clockmec and without impairing the visibility- .ofathe time indicatingmechanism.

Another object-of the invention is to provide a globe clock witha basearranged tosul pott and display direct reading time indicatingmeahsitogether with readily accessible manual meansfor adjusting orsetting the time indicating means as desired.

Other objects: and advantages will. heroine/liter appear andforpurposesof. illustration,,-butnotof limitation, arr-embodiment ofntheinvention, is shown on the accompanying drawing in which:

Figure; 1 is a verticalsectionalwviewof a ten.- restrial globe clockwith. portions. illustrated .in side elevation;

Figure 2' is anenlarged section'taken-substantiallyonthe line. 2-2otFigure 1;. and

Figure v3 is a fragmentary. verticatsectional view of an arrangementforman-ually operating the time indicating-mechanism.

The invention-is illustrated. as .comprisinga globe clock consisting ofa glassor-translucent sphere [0 made of. two parts .fittedtogetherdnoverlapping relation. On the outside of the globe may be painted orotherwise suitably. applied a map of the world, so that a lampon. theinside will illuminate the outside of the globe... The globe I0 ismounted on a hollow base III to which leadwires [3 having a connecti'ng.plug. IA .atthe outer end. On the base. [2 are provided switches f5 and'I6 which control a clock operating motor and the lamp respectively.

Mounted. for relative rotation on theplatform member. 22. is; a. ring toare secured a plurality of upwardly, and, outwardly extending rods .orarms 42. The upper extremities of. arms project through. openings means.431 integral with the inner surface oi. an annulusv or ring 414 ofvglass or other suitable translucent .or trans.- parent material... Thering 44 is vertically. disposed withlthe walls thereof. substantiallyparallet to the axisotthe globe. Hi and is arranged midwaybetweenltheopposite endsthereof. The outer, surface of the ring. (4 is formed withcall.- brations; numbers and. other i-ndicia. fordesignating the time.Thus, when the. lamp 321s lighted. the indicia onthe. ring, MTwilllherisihl'e from-the. outside oithe globe,..the,arrangement beingsuch that the corresponding time in different parts of the worldwillbe-indicated; The map-is ordinarily divided by lines of longitudeinto the-different time zones to enable. the. timein different places.to be readily observed.

Theinside of the ring 4| formed with an annulanseries otgear teeth 53with whieha .45 meshes; Pinion .45 is. mounted. on a verticalshait 54having a. hearing within a. boss 55. integral with a. plate. 56' which,is. removably secured. to and. spaced'from. the platform member 7.2 andserving. to locate the ring 4] ontthe plat- "form. shown,boltswithinthering 4]. secure the plate 56' to the;platform 22 in spacedrelation. A suitable clutch ,5?! is interposed between parts of theshaft 54 to enable, the W30 he turned or I adjusted. independently. ofthe upper portion or the. shaft 54. Mounted. on the. upper .end' of theshaft 541s a worm wheel which. a worm. 441 meshes. The worm 48'isfilxecltto a horizontally disposed: shaft 60- iorming an extensionotstheranmature. of theemotor. The motor 3'0 and associated parts ispreferably of sixty cycle synchronous type as ordinarily used forelectric clocks and therefore it is believed that further descriptionthereof is unnecessary. The motor is shown suitably mounted on theplatform 22 as by a depending supporting post.

The intermediate cylindrical casing l8 contains auxiliary or directreading time indicating means of any suitable character. has beenillustrated as including a shell or body 62 of sleeve form interposedbetween a top or cover portion 63 and a base 64 which is provided withthe projection i9. These elements are secured together by means such asbolts 65. A plurality of windows or openings 66, preferably three spacedequally, are provided around the circumference of the body 62 andthrough which indicia 6! are visible. The indicia are suitably appliedto the outer surface of rings 10 and II mounted for continuous rotationwithin the casing IS. The rings 10 and II are formed with annularseriesof gear teeth 69 and i2 respectively. The teeth 69 mesh with a pinion 68mounted near the lower end of the shaft 54, while teeth 12 mesh with agear 12 of asuitable gear train to rotate the ring H ten times fasterthan the ring 10. Thus it will be apparent that the indicia on rings 10and II are utilized to indicate the time in minutes by direct reading.

It will be readily understood that if so desired, a step by step ordelayed action movement may be imparted to direct reading indicia by anysuitable operating mechanism of that character, to replace the mechanismdescribed. It will also be understood that by adding a third ring itwould be possible to indicate the hour as well as the minutes shouldthis be desirable. As the hour indicia on the ring 44 may be made ofsuflicient size to be readily visible, the additional ring in the casingI8 is not essential.

From the above description it will be clear that the electric motorimparts turning movement to the ring 4|, the arms 42 turning the timeindicating ring 44 in the globe ill and rings 10 and H in the casing I 8relative to the globe In. When it is desired to inspect diiierent partsof the globe, the same may be turned, turning the time indicatingdevices and associated parts with it. 'In order to make an adjustment inthe relative position of' the time indicating rings, shaft 54 isprovided with an enlarged knurled portion 75, located outside of theglobe and casing I8, by which the time indicating rings may be turned asdesired in view of the clutch 51.

It is frequently desirable to use a manually operable globe clock, forexample, for demonstration purposes. In such event the arrangementfragmentarily illustrated in Figure 3, may be utilized. A shaft 54 isprovided with a pinion meshing with the teeth of ring gear 4|. The upperend of the shaft has a bearing in the box 55' while the lower end of theshaft has an enlarged knurled portion 75. By such an arrangement, ringgear 4| may be rotated byhand to indicate the correct time at a certainplace, on the glass time indicating ring within the globe. Subsequentrotation of the globe, and with the lamp lighted, will indicate thecorresponding time in other parts of the world.

It will thus be apparent that I have provided an arrangement whichenables the globe to be used in the usual manner, and in addition pro-Vides a direct reading clock, the parts of which do not in any wayinterfere with the surface of the map. In addition the arrangementissuch I I Such means Ition, especially as defined in the appended claims.
